Title: Apparatus for quetsching tubular goods
Inventor: HEITKAMP KARL HEINZ
IPC: D06B15/02
Filed: 1967-09-28
Abstract: 1,201,936. Textile treating apparatus. MASCHINENBAU HOSSMANN & STRAUSS G.m.b.H. 28 Sept., 1967, No. 44173/67. Heading D1L. An apparatus for quetsching tubular material, more particulary knitted tubular material, comprises at least two rotatable endless ring- shaped quetsching members 2, 3 pressed against one another, each quetsching member 2 or 3 being of circular cross-section, said members being so arranged on supports that they form between each other a nip having an endless line of contact, and whereby when a continuous length of tubular material is pased therebetween at least one member 2 presses against the inner surface of said tubular material and at least one other member 3 against the outer surface of the tubular material. In the embodiment shown in Fig. 1 the quetsching members 2, 3 comprises a pair of concentric rubber rings in a common plane each ring being held in position by its own set of pairs of support rollers 4, 5 or 10, 11. The rings are driven through a chain-bevel gear linkage acting on rollers 11 which rotates ring 3. The support rollers 4, 5 of the inner ring are mounted on a central member 9 which itself is located by a series of rolls 36 mounted on its lower half engaging between pairs of rolls 37, 38 fixed on the machine frame, e.g. a dyeing or sizeing bath, is led in flat condition into the lower end of the machine under a roller 40. The material then passes over the lower end of member 9, which causes the tube to open out, and up the outside of member 9. The opened tube then passes between roller 36 and roller 37, 38 after which it is caused to assume a funnel shape as it passes to the quetsching members, the ring 2 pressing against its inner surface and the ring 3 against its outer surface. Any liquid content in the material is thus squeezed out. To achieve and maintain the desired pressure between the two quetsch rings 2, 3, the roller 10, 11 supports are mounted on brackets slidable in slots in the machine frame, each bracket having a chain wheel 29 around which passes an endless chain 30 one end of which is fixed to a cylinder 32 and the other to the piston 34 of the cylinder, movement of the piston 34 varying the tension in chain 30 as desired. In an alternative embodiment (not shown) the brackets of the rollers 10, 11 are acted upon by a pair of flexible endless tubes filled with a fluid and which expand and contract radially according to the pressure within them. In other embodiments (not shown) the inner quetsching member consists of a single ring lying in a plane between the central planes of two outer rings comprising the outer quetsching member. Pressure is applied to the outer rings through rollers, a system of levers or a parallelogram linkage driven by a piston and cylinder arrangement.

Abstract: 1283047 Welding by fusion NEVILLE & WILLIS (WELDING & FABRICATIONS) Ltd 23 Sept 1969 [24 Sept 1968] 45226/68 Heading B3R [Also in Division F2] A composite flange comprises a flange of cheap metallic material, the front and rear faces of which are coated immediately adjacent the aperture with a more expensive metallic material by buttering (a technique involving the laying or spreading of the more expensive metal in molten form upon the flange). In the embodiment shown, a pipe coupling flange 1, e.g. of carbon steel, is machined so as to be rebated at 5 and 6 and a thin layer of high chromium content stainless steel (e.g. 25% Cr, 12% Ni) is welded to the surfaces of the rebates. Further welding with a lower chromium content stainless steel (e.g. 18% Cr, 8% Ni or 18% Cr, 10% Ni, 3% Nb) fills the rebates and stands proud of the flange (dotted lines). The flange is then remachined to remove excess stainless steel and provide a mating surface. A stainless steel pipe may be inserted into the flange and welded to the stainless facings so that there is no discontinuity of material in an assembled pipe run. Other materials, e.g. aluminium bronze and " Monel " (Registered Trade Mark) may be used for the coating.

Abstract: 1,182,716. Ink-ribbon mechanism. OLIVETTI UNDERWOOD CORP. 13 Oct., 1967 [14 Oct., 1966], No. 46923/67. Heading B6F. Supply spool mounting and construction.-A coil of ink-ribbon 35 is placed on circular elements 32, Fig. 9, forming an arbor extending from a flat panel 30 slidably fitted into a socket 17, Fig. 8, attached in a fore-and-aft direction to a side wall 10 of a typewriter. The flat panel has an extension 15 for easy removal from the socket 17 and has means to store a ribbon tension spring to fit in place of the spring 45 shown. Take-up spool construction.-The take-up spool comprises, an end-disc 51, Fig. 2, which is used to slot the spool into a bracket 52, on the left-hand side wall of the typewriter, a stud 50 with an annular groove 56, and two separate flanges 53, 54. Flange 53 carries, on its inner side, a collapsible multi-sectored core 60. Each sector 60 is formed integral with an arm 61 pivoted on a pin 62, e.g. from moulded plastic material. The arms 61 each carry a finger 63 which normally engage the full diameter of the stud 50 and maintain the core 60 extended but when the flange is moved axially to remove it from the stud the fingers drop into the groove 56 by the urge of a garter spring, whereby the cores collapse and permit easy removal of the ribbon. The other flange 54 is also held on to the stud 50 by detent fingers 55 and reinforcing spring fingers 68. Ribbon guides and tensioning.-From the supply spool 35 the ribbon is turned and guided towards the platen of the typewriter by a guiding saddle formed integrally with the plate 30. A tensioning wire spring 43 is also fitted on to the narrow end wall of the plate. Ribbon connection.-The flange 53 embodies a series of springy leaves 70 at graded distance from the axis which serve to self-attach the end of the ribbon to the spool. Ribbon-feeding.-When the take-up spool is lowered into guides 47 on the bracket 52 it engages a driving gear, (48, Fig. 5), rotated frictionally from a roller engaging the ribbon as it leaves the platen.
